sh: remove duplicate ioread/iowrite helpers

2025-03-11T09:41:18Z

The ioread/iowrite functions on sh only do memory mapped I/O like the generic verion, and never map onto non-MMIO inb/outb variants, so they just add complexity. In particular, the use of asm-generic/iomap.h ties the declaration to the x86 implementation. Remove the custom versions and use the architecture-independent fallback code instead. Some of the calling conventions on sh are different here, so fix that by adding 'volatile' keywords where required by the generic implementation and change the cpg clock driver to no longer depend on the interesting choice of return types for ioread8/ioread16/ioread32.

sh: Fix up the __raw_read/writeX() definitions.

2008-10-01T06:12:27Z

These were doing largely bogus things and using the wrong typing for the address. Bring these in line with the ARM definitions. Signed-off-by: Paul Mundt
